` Trl/1N 11F/vomit may concern,.-

y "Be it known that we, CLAUDE POYET and GEORGE B. M. GOODWIN, citizens of the United States,and residents of the city,county,

- and State of New York, have invented certain new and useful Improvements in Confectionery-Coating Machines, of whlch the following is a specification.

Our invention relates to machines for coat-` ing confectionery or the like.- lVhile maa chines may be constructed in accordance with.

t-he principles of our invention for coating vai-iousforms and kinds of confectioneryY with various materials, our invention as to some of its features is v`more particularly adapted for y'coating confectionery, nuts, &c., with chocolate. f

' Our invention has for an object to provide l av machine which is more rapid and'morc resoV 'liable in operation as regards the quality andA quantity of the product than any of the machines heretofore devised.

Other objects of' our invention are to provide a machine which is simple in construction, which requires but little attention, and which at the same time produces a product which is more uniform and more nearly approaches in appearance hand-coated confecproduct of any of the prior machinesff These and other objects of our invention will more fully appear from the following description; i f

Our invention consists in the novel parts, improvementaand combinations herein shown and described.

'lhe vaccompanying drawings, which are referred to herein and form a part hereof, illus- .trate one embodiment of the invention and servein connection with the description here- 'in to explain'the principles of the-invention and the best mode contemplated by us of carrying the invention into effect.

Of the drawings, Figure 1 is a side elevatiorr of a mach-ine constructed in accordance,

with our invention. Fig. 2 is a longitudinal section ot' the portion of thc same shown at the right'in Fig. 1.- Fig. 3 is a plan view of the same. Figs. et to 8, inclusive, are side and 'plan views illustrating certain details of dul machine on an enlarged scale.

A machine constructed in accordance with the principles of our invention comprises in general the combination of an endless carrier having closely arranged throughout its length and breadth open skeleton holders for the confectionery, means for applying the coating material to. the confectionery in the carrier, and means for receiving the coated con fertionery as it, is delivered from the carrier.

'ln accordance with one feature of the invention the means for, applying the coating nia- `terial comprises atank with means for maintaining a substantiallyv uniform level of the coating material in the tank and means for so directing the carrier through the tank as to submerge the confectionery in`the coating material.

In accordance with' another feature of our invention the holders for the. confectionemY are inverted after they leave the means for' applying the coating material and a suitable carrier is provided to receive the coated confectionery as it is delivered from the holders.

Referring to the drawings in detail. l represents a suitable framework upon which tinl various parts of the machine are operatively mounted in cooperative relation. 'lhe'endless carrier for receiving the cores or "centers of the confectionery and conveying them through the various steps of the coating process consists, in accordance lwith thc embodiment of our invention illustrated, of a pair of endless chains or belts "Q, which are mounted at opposite sides of the machine upon suitable sprocket-wheels carried by the transverse shafts 3 and 4, journaled at opposite ends 1of the frame'. Extending transversely of the machine and secured at their opposite ends in the chainsare a se- 'ries'of bars or rods 5, each of which is provided with a series of skeleton or open-work baskets or holders 6. These holders may be made ofv any suitable form to correspondl to the shape or configuration of the cores which are to be coated. Theholders are openat-one the ends 8 being connected by the convolutions 9, which embrace the rods and are preferably rigidly fixed thereto, as by means of solder. The-holders 6 are preferably closely arranged along the rods 5, and the rods 5 are arranged at close intervals along the chains 2, there preferably being a rod 5 for each alternate 'link .in the chains. vided a carrier having a large number of holders for the confectionery, the capacity of the machine being limited only bythe width of the carrier and the speed at which it is driven. vFor the purpose of driving the carrier the shaft 3 is provided at one end with a sprocketwheel 10, whichireceives motion from the main shaft 11f by means of a chain 12, which issuitably guided by the intermediate sprockets 13 and 14.

, As far as some -of the features of our invention are concerned any suitable means may be provided for applying the coating material to the confectionery in the carrier.' Preferably, however, a suitable dipping-tank 16 is arranged adjacent to the upper stretch of the carrier 2 and means are provided for so depressing the carrier within the tank 16 as to cause the confectionery to be submerged in the coating material during the passage of the carrier through the tank. The means shown for vdepressing the carrier consists of a series of stud-rollers 17, which are arranged to engage the, chains 2 and cause them to travel in a curved path below the level of. the coating material in the tank 16, the chains being guided into and out of the tank by the sprocket-wheels 18 and 19, respectively. Any suitable means may be -provided for preventing the corepieces from floating out ofthe holders 6 as the latter pass through the coating material. Preferably, and as shown, a second endless carrier is provided for this purpose, the same consisting of a pair of belts or chains 20, mounted on suitable sprockets 21 and 22, arrangedabove the tank 16. The chains 2O are depressed to conform'to'the path of the carrier 2 by a series of stud-rollers 23. Mounted at their opposite ends in the chains are a. y

series of transverse rods or bars 24, which are spaced to'correspond with the bars 5. The bars 24 are provided with sets of lingers 25, which are spaced along the bars 24 to correspond to the holders 6 on the bars 5 and are adapted to register'with and close the open ends of the holders 6 during the passage of the latter through the tank 16. The chains There is thus pro` 2O may bedriven by any suitable means, as by cham 26 and sprockets 27, which receive motion from the chains 2.

Any suitable 'means may be provided to maintain -a supply of coating material in the tank 16. We preferably employ a suitable pump to elevate the material from a supply-tank 30, arranged near the base of the machine, an overliow being provided from the drippingtank 16 back to the supply-tank to keep the Amaterial in constant circulation. The form of pump illustrated consists of an endless belt 31which is mounted on a pair of wheels 32 and 33, the former of which is located in the supply-tank and is mounted on the main shaft l1 and the latter of which is mounted ina suitable casing 34, arranged above the tank 16J The belt 31 is provided at suitable intervals with diaphragms or buckets 35, the wheels 32 and 33.being provided with suitable recesses to accommodate the buckets 35. rIhe tank 30 and the' casing 34 are connected by tubes 36 and 37, which form passages for the opposite strands of the belt 31. The tube 36 .is large enough to permit free downward passage of the buckets 35, but the tube 37 is so Vrestricted from its lower end to a point near the top as to closely fit the buckets 35, and thus enable them to convey the material upwardly from the tank 30 to a spout 38, which discharges the material into the tank 16. In order that the material may ybe kept in circulation and in order that a substantially uniform level may be maintained in the tank 16, an overflow-passage 39 is provided between the tank and the tube 36. v

For the purpose of agitating the carrier as it leaves the tank 16, so as to shake off the excess of coating material from the cores and the holders, the following mechanism is provided: A pair of shafts 40 and 41 are journaled in the frame above the carrier 2.V Each of these shafts is provided at each end with a suitable cam 42, each of which cams engages a lever 43, suitably pivoted on the frame. The levers 43 at opposite sides of the machine are connected by links 44 and 45 with the opposite ends of the transverse bars 46 and 47. The bars 46 and 47 pass underneath the' upper stretch of carrier 2 and are provided with longitudinal track-bars 48, which lie beneath the chains 2. As the shafts 4() and 41 rotate, the cams 42 will act to lift the chains 2 and let them drop back suddenly, soV as to jar off the surplus coating material. Sprocket-wheels 27 and 49 are arranged near the opposite ends of the track-bars 48 to prevent the chains 2 from being displaced by the action of said bars.

The shafts 40 and 41 may be driven from the main shaft 11 by a chain 50, the two shafts being connected by a chain 51.

, To assist in the removal of the surplus coating material, a pair of fans 53 and 54 are provided, the same being housed in a casing 55 IOO IIO

anddriven :from'any suitable sourceof power vbya belt .36.1l Inforder todirect the airufrom;

the fans againstthe coated confectioneryin the carrier; suitable guides 57'and'58lmay'be provided. i

' `Asfar as' some-,of thefeaturesof ourinvention are concerned any; suitable means kmay be provided toi receive the coated confectionery as it is delivered from the holders 6.` In accordance with this Vfeature of our invention we employ'a conv-eyer in the form of an endless belt or apron 60,- which is preferably arrangedtov make contact with the outer open ends of the holders 6 while the latter are being inverted by, passing around the sprocketson the shaft Aa By reason of this construction thefcoated confectionery is nicelyl delivered .into the apron 6() with the proper side up and at uniformly-spaced intervals. For thepurpose'of insuring the delivery ofthe confectionery from the holders the carrier 2 is guided away from the apron 60 at a suitable angle by the guidesprockets- 61, and means are provided, to tapthe back of eachv of the bars 5 as theholders thereon begin to recede from the apron in order to loosen any'of the pieces vof coated confectionery which -may tend to stick in the holders. The means shown for this purpose consists of a transverse bar 62,

which is mounted on arm 63, carried by rockshaft 64. The bar 62 is raised and allowed to drop back at suitable intervals by means of a cam 65, driven from shaft 4by suitable gears 66 and 67, said cam being adapted to engage an arm 68 on the shaft 6ft. Atension-spring y 69 may be so connected to the arm -68 as to.

increase the impact of the bar 62.

For thevpurpose of marking the coated confectionery we may provide an intermittentlyoperated device to make contact with each 'line of the coated 'confectionery as it rests on the apron 60. This device consists of a bar vor a series of arms 70, which are mounted on a rock-shaft 71, said shaft having anarm 72, adapted to be'operated by the cam 65 or by another cam on the same shaft. By setting the arms 7 0 so that they will touch the tops of the pieces -of coated confectionery and by giving the contact portion of the arms a suitable conliguration they will act by raising slight ridges on the coating to give the pieces any vdesired mark.

The apron vis guided around and in. contact with the carrier by suitable guide-pulleys 7 3 and 74. The` apron 60A maybe extended beyond the machine and throughl a cooling apparatus, if desired, to any suitable point of delivery. For the purpose' of assisting the driving of the apron a series of rollers 75, 76,

.. and 77 are arranged to engage the lower stretch of thek apron, the same being located near the left end of the machine, as shown`in Fig. l.

@One of the rollers, 75, isdriven 4by the chain 12 andthe intermediate roller, 7 6, and is pref- `(ti-ably,,made ad justabler so as fiio yregulate-the `tension of the apron.

vFor the purpose `of collecting the dripfrom thecanrier 2 and ,returning the same tothe tank-.30a suitable drip-*pan -80 is arranged 4beneath :thefcarrier-the bottomof thet p an being: sloped tor/a low point .Opposite the tube 36 and connected thereto ubyfay passage 81.

With the object in view of providing .ample room for the filling of the holders in the carrier2 with cores the carrier is extended a cori--l siderable distanceto the left, as seen in Fig. l, or in advance of the dipping-tank `16, so as to provide space for several 4feeders to get at the carrier. To prevent the dust or powder which inevitably-drops from the cores as they 'arie placed in the carriers from falling into vthe drip-pan 80, where it would contaminate the coating material, a shield-plate 82 is arranged beneath the upperstretch of the carrier 2.

The operation of the machine having been fully described inconn'ection with the description of the various parts thereof, 'further description of the operation will be unnecessary.

-Ourinvention in its ,broader aspects is not limited to the precise construction shown nor to the particular construction by which it may be lcarried into effect, as many changes may be made in the construction without departing from the main principles of the invention and Without sacrificingits chief advantages.
